''Life with Harry was certainly never dull,'' Steve Stone writes, and he proves the point in his anecdotal biography of the legendary sportscaster Harry Caray, who died last year. For 15 years, Caray and Stone were the broadcasters for the Chicago Cubs. They were not exactly give-and-take sportscasters: ''Harry did most of the talking.'' Caray acknowledged his garrulousness early in the 1997 season: ''I'm getting older every day. I don't know how many words I have left in me, so I better use them all now.'' Stone says he just watched as Caray extricated himself from silly on-air problems, like talking into a lamp instead of the microphone or turning off the sound by leaning on the cough button for a couple of minutes. Mispronunciations came naturally to Caray, and he knew it. In a game against the Colorado Rockies, Frank Castillo pitched against Vinny Castilla and Pedro Castellano. ''Are you kidding me? They did this to me on purpose,'' Caray yelled. Stone recalls Michael Jordan's refusal to sit in the broadcast booth: ''I love Harry, but I don't want to go on the air and have him introduce me as Michael Jackson.'' Peggy Constantine
